combobox and GridGroupingControl

[Ray]

I was trying to load a GGC with comboboxes. However, I found that I had to load the GGC before I could use it in a button callback. Otherwise, I receive a "Object reference not set to an instance of an object." error. I am not sure why I have to load the GGC in the constructor. I have included an example. Why do I have to load the GGC early?

Thanks

Ray.

Hi Ray,

Try calling the ReInitialize method after setting the underlying datasource of the grid. Please try the modified attached sample and let me know if this helps.

_Grid.DataSource = dt;
_Grid.Reinitialize();

Here is a modified sample.
